There are more than 30 described species in genus ''Bacteriastrum'', but many of these are not currently accepted, and new species are still added to the genus.Sarno, D., Zingone, A. & Marino, D.

Description
''Bacteriastrum'' is a widely distributed marine, planktonic genus. This genus is often associated with ''Chaetoceros
''Chaetoceros'' is a genus of diatoms in the family Chaetocerotaceae, first described by the German naturalist C. G. Ehrenberg in 1844. Species of this genus are mostly found in marine habitats, but a few species exist in freshwater. It is ...
'' but differs in radial symmetry and fenestration of setae. The colonies tend to lie in girdle view, and the cells are separated by the curvature of the basal part of the setae, leaving a small gap between the cells. The cells are cylindrical and linked to form filaments. Each cell has several long, radiating setae which may be simple or bifurcate (branched), the setae from adjacent cells are fused. The plastids are discoid. At least one species, '' B. solitarium'', exists as single cells.Round, F. E. and Crawford, R. M. (1990). ''The Diatoms.
